A mesura que els vaixells superin els doldrums trobaran vent del ESE al sud de l'equador. Aquells que encara s'hagin d'enfrontar al pas per les calmes equatorials es toparan amb un període més lent d'encreuament durant les pròximes 12-24 hores, però després s'espera l'estrenyiment dels doldrums incrementant les possibilitats d'escapar ràpidament cap al sud.

4) Widespread showers and thunderstorms are occurring, especially along
the northern doldrums boundary. There is a patch of lighter breeze in
the doldrums from about 24W to 27W. This area is expected to fill
5) South of the Doldrums, winds shift ESE and build light-moderate. ESE
tending SE winds are expected by 1S, becoming Moderate around 4S.

moderate to fresh NEílies. There will be a more left-shifted (NNE/N)
breeze east 25W.

further north toward 20W. The northern boundary may become more difuse
as the day progresses, especially west of 24W.
4) The southern boundary will lie around 2N west of 24W. East of 24W, the
southern boundary will be closer to 1N.

moderate west of about 28W. Lighter patches are likely between 24W and
28W. Very light and variable conditions east of 24W.

moderate, especially west of 25W. Moderate ESE winds will be south of

00Z WEDNESDAY (14-JAN-2015):
1) North of the doldrums, trade winds light-moderate NNE at 20W
increasing and veering moderate NE at 30W.
2) The doldrums will be shifting south once again. The northern boundary
will be near 2N/30W - 4N/25W at 5N/20W. The southern boundary will be
along about 1N.
3) Within the doldrums, light and variable conditions east of 23-24W.
Otherwise NE tending E west of 25W. The zone will be narrowest with
stronger cross-flow west of 28W.
4) South of the doldrums, light moderate ESE trade winds from 1N to 5S.
5) Moderate ESE/SE trades 5S to 10S.
6) Between 10S and 22S, mainly moderate ESE trade winds in the zone
between 25W and 35W. Note winds will be more SE east of 25W and more
ESE/E west of 30W.
7) The South Atlantic high (1022mb) will shift a little west to 26S/28W.
00Z THURSDAY (15-JAN-2015):
1) Northern doldrums boundary will be shifting south to 4N/20W ñ 3N/25W ñ
2N/30W. Doldrums will be wider with lighter winds within them east of
25W. East of 25W, light Eíly increasing to light-moderate at 30W.
2) The southern doldrums boundary will be sitting near 1N, except closer
to the Equator east of 23W.
3) South of the Equator, ESE veering SE south of 2S.
4) A moderate to fresh ESE trade wind will be west of 27W and south of 5S.
East of 27W, winds will ease and veer more SEíly.
